About this tour
When Ben from our team did this snorkeling run out of Ko Samet, we found Thalu Island a proper quiet alternative to the packed reef spots. The boat ride's short, and you get three solid hours on the water to poke around coral gardens, wade through shallows, and mess about on white sand before heading back. It's the kind of trip that works if you want to skip the resort pool but aren't after an all-day expedition — plenty of families and couples were doing the same.
Highlights
- Free underwater photography service captures your actual snorkeling without the GoPro tax
- Arch rock formation provides distinctive landmark and natural frame for photos
- Floating board option lets non-swimmers get close to coral without full immersion
- Hotel pickup from Ko Samet cuts out transport logistics before departure
- White-sand beach stretches give proper downtime between water time
- Small-group dynamic means guides actually notice if someone's struggling
- Freshly cut pineapple and watermelon (not sad pre-packed fruit)
What to expect
Ben headed out early morning, picked up from his hotel and taken straight to the boat. The ride to Thalu takes maybe 20 minutes of choppy water — bring seasickness tablets if you're prone. Once there, you get a quick safety rundown, then you're in. The reefs are decent; hard corals and the usual wrasse, parrotfish, nothing rare but satisfying. The arch rock is legitimately worth the swim over. You'll likely share the spot with one or two other boats, not swarming like Koh Larn.
The pace is relaxed. Snorkel for an hour, float on the board, have a breather on sand, eat fruit, snorkel again. Three hours feels about right — long enough to explore without getting waterlogged. Guides here don't rush you through. The gear's solid (though no fins included, which some people miss for reef navigation). Water clarity depends on season; we caught it decent but not gin-clear.

Good to know
If you're Ko Samet–based and want an easy half-day out without booking a tour operator in town, this ticks boxes. The floating board means non-confident swimmers can still see coral. Free underwater photos are genuinely useful. Fruit and water included beat paying 200THB markup at resort cafes.
National Park and coral reef fees (300THB total) aren't in the tour price — budget extra. No fins is annoying if you're keen on reef coverage; the arch rock requires decent swimming fitness. Boats run weather-dependent, so rough season (May–October) might cancel. Early start suits roosters better than sleepers. Only moderate fitness needed, but you're in water 90 minutes of the three hours — not a float-and-relax affair.
Reef-safe sunscreen (seriously), a light rash guard, towel, any personal medications. Included: water, snacks, life vest, board, gear. Group size typically 8–12 people. Peak season (November–February) books faster.
